4 Claims.

This invention relates to a gathering organization for loading machines,this application being a division taken from my co-pending applicationSerial No. 668,046, filed April 25, 1933.

The object of this invention is, to provide a gathering organization ofimproved efficiency especially in the respect that it will have aminimum of shattering effect upon the coal in its actuation of same fromthe floor of the mine onto the gathering elevator whereby it is conveyedaway from the point at which the coal is mined; another object is toprovide a gathering organization which will cause the coal to beretained upon the conveyor flight at the gathering end of the machine,instead of overflowing laterally therefrom back onto the mine floor, afault which is common to many of the gathering organizations heretoforein use.

My improved construction is clearly illustrated in the accompanyingdrawing in which: Fig. 1 is a plan View of the lower end of a gatheringand elevating conveyor of a loading machine, the general use of which isthe gathering and elevating of coal from the mine floor and the transferof same to a mine car or another conveyor.

Fig. 2 is a section of Fig. 1 upon the line II-II as if the section weretaken on line II-II.

Fig. 3 is an outside, side elevation of the gathering arm, the discwhich operates the same and the adjacent portion of the deck-plate ofthe frame.

The construction shown in said drawing is substantially as follows:

The portion of the gathering and elevating conveyor 1 which is usuallytermed the shoe, operates either in close proximity to or in contactwith the floor of the mine, adjacent to the coal to be operated upon;the remainder of the elevating conveyor, which extends upwardly from themine floor comprises a frame work consisting of an elevator channel 2and the deck plates 3, 3; positioned at a point intermediate said shoeand the lower end of said deck plates, are two revoluble discs 4, 4, oneat each side of said channel 2, said discs 4: are each driven by meansof a bevel gear 5 and an intermeshing pinion 6, which pinion is rigidlymounted upon a revoluble foot-shaft 7, which shaft is, in turn, revolvedby the conveyor chain or apron which travels within said channel 2.

Each of said discs is provided with a perpendicularly-extending crankpin 8 adapted for the actuation of a gathering arm 9, each of which armsis provided, in proximity to its lower this application July 27,

end with a crank-pin bearing 10 and its opposite upper end with abearing 11 for the reception of a pin 12 which is carried by the freeend of an oscillating delineator-lever '13 whereby the shape and extentof an assumed diagram, as 14, is delineated by the point of an implement15 which is carried by said gathering arm; said diagram indicates thearea swept by said implement 15 from which area material is gathered andactuated onto the conveyor flight; the pivotal end of said lever 13 iscarried by a bracket 16 which is aflixed to one of the structuralelements 17 of the conveyor frame, and, as shown in the drawing, saidbracket 17 is located beneath the deck-plate 3 upon its respective sideof the frame of the elevator.

Said gathering arm 9 is provided upon its inner side or face adjacentthe channel 2 with a broad flange 19, the inner face of which extendssubstantially perpendicularly to the upper adjacent face of the adjacentdeck-plate 3; the lower edge of said flange being arranged in closeproximity to said deck face, whereby it is adapted to perform the twoimportant functions of preventing coal or other material which mayoverflow from channel 2, from falling from the conveyor and also toactuate such overflowing coal back into the conveyor channel onto theconveyor belt or chain, as the case may be.

It will now be readily noted that, as a disc 4 revolves it imparts acircular line of travel to the gathering arm bearing 10 and to theadjacent portion of said arm and that this motion will cause the upperend of said arm to travel along the arc defined by the dotted line 18and also to have a laterally vibrating movement, whereby any materialwhich may overflow from the conveyor channel onto the deck 2 will beactuated back into said channel; this vibrating movement is uniformthroughout its extent and furthermore it is such as to exert noshattering effect upon lumps of coal with which it comes into contact,and because of this, it is free from the degrading effect upon coal thatis produced by other types of gathering arms.

I claim the following:

1. In a gathering organization for loading machines, a conveyor frame, aconveyor carried by and operative in said frame, a deck plate positionedlaterally of said conveyor, a rotatable disc adjacent the receiving endof said conveyor, with its upper face flush with said plate, a crank pincarried by said disc, a gathering arm operably connected adjacent one ofits ends to said pin with its lower face in close proximity to theadjacent face of said disc, and a delineator arm connected at one of itsends to the other end of said arm, the other end of said delineator armextending beneath said plate and connected to a pivotal pointthereunder.

2. In a gathering organization for loading machines, a conveyor frame, aconveyor flight carried by and operable in said frame, deck platespositioned laterally of said conveyor, rotatable discs positionedlaterally of said conveyor adjacent the receiving end thereof, a crankpin carried by each of said discs, a gathering arm operably connectedadjacent one of its ends to each of said discs and a delineator arm foreach of said gathering arms, said delineator arms being positionedbeneath said deck plates with one end of each thereof connected to itsrespective gathering arm and its other end connected to said frame.

3. In a gathering organization for loading machines, a conveyor frame, aconveyor flight carried by and operable in said frame a deck-platepositioned laterally of said conveyor, a rotatable disc adjacent thereceiving end of said conveyor with its upper face flush With the upperface of said plate, a crank pin carried by said disc, a gathering armoperably connected adjacent one of its ends to said pin with its lowerface positioned in close proximity to the adjacent faces and said plate,the innerface of said gathering arm being provided with a flangeextending perpendicularly to said disc and deck faces and a delineatorarm connected at one of its ends to the other end of said gathering arm,extending beneath said deck plate and oscillatively attached to saidframe thereunder.

4. A gathering organization for loading machines comprising incombination, a conveyor frame having a conveyor therein and alaterallyextending deck plate at each side of, adjacent the lower end ofsaid frame and conveyor, a gathering arm carried by each side of saidframe operable over said deck plates respectively, one end of eachofsaid arms being arranged to actuate material onto the lower end ofsaid conveyor, and the other end thereof to replace material onto saidconveyor which has become displaced from said conveyor onto said plates,each of said arms being provided upon its inner face with aperpendicularly disposed flange of equal height throughout the linearextent of said arm, a de lineator arm for each of and attached at one ofits ends to the upper end of its respective gathering arm, the other endof said delineator arm extending beneath its respective deck plate andattached to said frame therebeneath, and driving means imparting to saidconveyor and to said arms their necessary mode of operation.
